    Why didn't you figure this out???

    I must really apologize for my twisting your arm into commenting here. I realize I've raised an issue you don't want to investigate. And I'm sorry you have no desire to understand it.

    1.) I said the inside of the computer case is insulated. Did you see what I'm using for a computer case. It's a SEALED Pelican 1780 Transport case.

    2.) I'm basically turning that case into an INSULATED mini-freezer.
    3.) The EVAPORATOR INSIDE the computer is what will cool the gel-packs.
    4.) The gel-packs (once installed) will NEVER leave the inside of the case.
    The deeper the temperature the gel-packs are frozen to, the longer it take for them to heat up:

    Consequently the internal temperature will remain more stable over a longer period of time.

    EVERYTHING that I've stated in this post, I've stated here before.

    Physicists are still at a loss to explain why and how vortex tubes work. So don't quote me your understanding of physics, when those more qualified than you have no idea what's going on inside of one. Again, if you read about that, you would have seen that fact repeated in almost every place that vortex tubes are discussed by physicists. For crying out loud! Wikipedia would have told you this!

    I meant exactly what I said about the intercooler. Just because I used the words INTERCOOLER and EVAPORATOR in the same sentence, doesn't mean I was talking about the same thing.

    1.) I'm creating a separate cooling loop using the smaller compressors. Those four Rechi compressors will use the intercooler (because of the intercooler's sheer size) as their condenser. The evaporator for the external cooling loop will be the heat-exchanger for BOTH the warm internal refrigerant and the cooler external refrigerant will flow through. That heat-exchanger is replacing the condenser for the internal cooling loop.
    I'm using the external condenser (the intercooler) and it's associated refrigeration system to cool the internal heat-exchanger and it's associated refrigeration system. The two separate systems only share the heat-exchanger in common.

    2.) No, you don't understand me! If I haven't explained this well enough by now, I don't know what else to say. The four Rechis are inside the computer case. The only thing connected to the four Rechis, is the external condenser (the intercooler). And since I know you would like nothing more than to point out one intercooler is likely not enough, I already intend to use more than one. I just don't know yet if that will be two or four intercoolers connected to create one massive radiating body.

    3.) The velocity of the gas that spins inside a vortex tube is relative to the pressure of the inlet gas. The higher the pressure, the higher the speed of rotation. The higher the speed of rotation, the greater the separation of temperature between the hot and cold gas leaving the vortex tube.

    But you've made a good point. I've not seen exact numbers on whether the heated gas's temperature is lower or higher than before. It may be that the heated gas is at a higher temperature. In other words, I don't know if the change in temperature is equally divided between the cold and hot gases generated, or if the temperatures of both are lowered. But one thing is known, the cold gas generated by the higher rotational speed is much lower than with the typical pressure of 100psi.

    4.) Instead of being sarcastic, if you read some of the documentation on vortex tubes I've posted here, you would have seen that this has already been done using turboexpanders or pulse-tubes. In one study, the vortex tube was connected to a pulse-tube, and the temperature of the heated gas was cooled and sent back into the stream. Turboexpanders do the same thing with temperatures much higher than what a vortex tube produces. In fact, turboexpanders are used to rechill superheated steam to sub-zero temperatures. Again, you probably haven't looked those up either. There's nothing of gravity to do with this, other than you wanting to be sarcastic!

    5.) Snippy? Every question you've posted here depends on the function of the vortex tubes and their ability to cool gases.

    6.) And let me REPEAT this again. The ONLY thing on the exterior of the computer case, is the CONDENSER.

    7.) What I'm doing will resemble this somewhat:


    An even better explanation would be this. Take this image above and duplicate it, having one image above the other (I've already done it, so you won't have to imagine it!). So the the condenser at the top of the bottom image and the evaporator of the top image is the heat-exchanger shared between them that I spoke of. That should hopefully make better sense. Because there are in fact two separate refrigerant loops at work here.

    The (Rechi) compressor for the top image will be the external condenser refrigerant system.
    The bottom image's condenser and the top image's evaporator are BOTH replaced by a SINGLE heat-exchanger between BOTH images.
    The (Unknown) compressor for the bottom image will be the internal refrigerant system.
    The topmost condenser is the only thing that's outside of the system environment.

    I really have to apologize if English isn't your first language! I can understand then how reading English documentation would be a problem for you.
